Struct Scan 

pub struct Scan {
    pub body: Callee,
    pub init: LocalValueId,
    pub src: LocalValueId,
    pub captures: Vec<LocalValueId>,
}

A total left-scan out[i] = acc_i+1 where acc_i+1 = body(acc_i, src[i], captures…) and acc_0 = init. The result is [U; N] where N is src’s length and U is the body’s return type (also the accumulator’s type).

Fields

body: Callee

The pure per-element fold function, applied at each lane. A symbol, not an operand — exactly like a direct call’s target. Binary in (accumulator, element).

init: LocalValueId

The initial accumulator value (acc_0).

src: LocalValueId

The array value scanned over.

captures: Vec<LocalValueId>

Loop-invariant values the body closes over (the accumulator and element are supplied per-lane by the scan itself). Empty for a closed body.

Trait Implementations
